漂白粉或漂粉精片有效氯含量的测定,以硫代硫酸钠滴定法测定漂白粉有效氯含量,所需设备较多而且难得,手续麻烦,计算复杂,在部队基层单位很难推广运用。自从有人报告应用2%的蓝黑墨水盐酸溶液测定漂白粉有效氯含量,引起了广泛的注意,1965年初我们也应用蓝黑墨水测定漂白粉或漂粉精片有效氯含量,经过反复实验获得了满意
Determination of available chlorine bleaching powder or bleaching powder tablets, sodium thiosulfate titration to determine the effective chlorine content of bleaching powder, the required equipment more and rare, the procedure is cumbersome, computational complexity, it is difficult to promote the use of units in the grassroots units. Since it was reported that the determination of the effective chlorine content of bleaching powder by using 2% blue-black ink hydrochloric acid solution has drawn wide attention, we also used blue-black ink to determine the effective chlorine content of bleaching powder or bleaching powder at the beginning of 1965, and obtained satisfactory results through repeated experiments
